Acoustic Glass Fiber Acoustic Wool

Product Characteristics

Centrifugal glass wool has good sound absorption performance for mid and high frequencies. The main factors affecting the sound absorption performance of centrifugal glass wool are thickness, density and air flow resistance. Density is the weight of material per cubic meter. Air flow resistance is the ratio of air pressure and air velocity on both sides of the material per unit thickness. Air flow resistance is the most important factor affecting the sound absorption performance of centrifugal glass wool. If the flow resistance is too small, it means that the material is sparse, the air vibration is easy to pass through, and the sound absorption performance is reduced; the flow resistance is too large, it means that the material is dense, the air vibration is difficult to transmit, and the sound absorption performance is also reduced. For centrifugal glass wool, the sound absorption performance has the best flow resistance.

Use glass wool of different bulk density to be stacked together to form a form with a gradually increasing bulk density, which can obtain a greater sound absorption effect. For example, stacking a 2.5cm thick 24kg/m3 cotton board with a 2.5cm thick 32kg/m3 cotton board will have better sound absorption than a 5cm thick 32kg/m3 cotton board. The 24kg/m3 glass wool board is made into a 1m long wedge with a triangular cross section. The surface density of the material gradually increases, and the average sound absorption coefficient can be close to 1. Glass wool is a product made by using unique centrifugal technology to fiberize molten glass and add an environmentally friendly formula binder mainly composed of thermosetting resin. It is a product made of glass fibers with a diameter of only a few microns. Flexible glass fiber products, and can choose moisture-proof veneer online composite according to the different requirements of customers. Because it has a large number of tiny air gaps, it plays the role of heat preservation, sound absorption, noise reduction and safety protection. It is a building The best material for thermal insulation, sound absorption and noise reduction. Unique advantages, unique technology, the rebound rate after compression packaging is 99.2%. The soft and slender glass fiber minimizes flying floc during construction.
